These options reflect the network provisions for this SPID. If the BRI was
purchased with different services provisioned for the SPIDs, then the call
must match the services supported.
STRIP MSD
Write security: 3; Read security: 5
Strips a selected quantity (choose from N
ONE
, 1, 2,and3)oftheMostSignif-
icant Digits (MSD) of a dialed number prior to being forwarded out of the
port.
E
XAMPLE
:
A network port could be set to accept all calls beginning with 9 (9$), and
then with S
TRIP
MSD set to 1, all digits would be sent toward the network
except the leading 9.
SOURCE ID
Write security: 3; Read security: 5
Simplifies the creation of a DIAL
P
LAN
in applications where the criterion for
switching calls to a certain endpoint is a function of which endpoint origi-
nated the call.
• Default value = 0. The default ID for all endpoints is 0 and for all accept
numbers is 0. With default values, all calls are routed based only on the
dialed number.
• Multiple endpoints can have the same S
OURCE
ID.
• When creating the C
ALL
A
CCEPT
list, specify a S
OURCE
ID(s)aswellasa
dialed number or range of dialed numbers to accept.
E
XAMPLE
:
An application requires that all calls that originate from Port 1 of the
ATLAS 550 in Slot 1 be switched to Port 2 of that same module. Assign a
unique Source ID (e.g. 7) to Port 1 of the module, and then configure Port 2
to only accept calls from that unique Source ID (7).
CREATING DIAL PLANS—EXAMPLES
The ATLAS 550 D
IAL
P
LAN
acts as the numbering plan for switched connec-
tions. This menu defines to the ATLAS 550 the phone numbers and features
associated with dual-tone-multifrequency (DTMF) dialing, Primary Rate
ISDN (PRI), and Basic Rate ISDN (BRI). To operate as a switch, the ATLAS
550mustbeabletoterminatenetworkconnections(Network terminations)
and emulate the network onto other termination equipment (User termina-
tions).
S
TRIP
MSD does not affect C
ALL
A
CCEPT
criteria. All of the digits
(including the MSDs that are subsequently stripped) are used as
accept criterion.
